The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Honestly, for the first few days, it’s pretty grim. There’s a whole lot of poor surf and messy wind, so you’re not missing much if you give it a miss until later in the week.
The best window we’ve got in the whole 16-day run is Thursday morning, the 10th of September. Karramarro is looking like the standout. It’s a point break, best when the swell is from the NW, which is exactly what we’re getting. That morning, the wind goes glassy, the swell is a clean 4ft, period of 10 seconds, and it’s packing moderate energy (355). That’s proper point break conditions, glassy and lined up. Keep in mind, this spot is inconsistent and doesn’t break often, so when it does, it’s a real treat. It’s fairly exposed to the swell, and crowds are likely, so get in early.
Another one to circle on the calendar is Sunday morning, the 13th of September. We’ve got a solid 5ft NW swell, long period of 13 seconds, and glassy conditions. The energy is strong (666). That’s a proper groundswell, and on a point break like Karramarro, those long-period waves will wrap in nicely. Just be aware, with a period that long, it can run a bit straight on a beach break, but here it’s a point, so it should be sweet.
Then there’s a bit of a gap, but look ahead to Monday morning, the 21st of September. That’s over a week away, so take it with a grain of salt, but it’s showing 5ft from the NW, period of 11 seconds, and glassy again. Energy is strong (611). That’s a promising call for a clean, punchy session.
The rest of the days are a mixed bag of smaller surf, cross-onshore winds, or just not enough energy to get excited about. The 11th, 12th, and 15th through 20th are mostly small, weak, and messy. Not worth paddling out for.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Karramarro is 3 km (2 miles) from Zarautz. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Zarautz. Zarautz has rooms for a wide range of budgets as well as car hire and transport links.
